What new event or development stage was introduced in the latest version of the component or system lifecycle?

In the latest versions of iOS and SwiftUI, a lifecycle stage related to the scene's state has been introduced — for example, methods associated with the UIScene lifecycle, such as sceneWillEnterForeground and sceneDidEnterBackground. This allows for more precise management of the application's state at the level of individual windows (scenes), rather than just the entire application.

Additionally, SwiftUI introduced a new lifecycle using the App protocol, where you can track the application's phases through .onChange(of:) modifiers for scene and application state, simplifying state and resource management.
